Jump animation will not play

I’m making a 2d platformer, and I’ve already figured out how to make the player character jump. However, I want to play a jumping animation for whenever the player jumps. Here is my current script, though it should be noted that I’ve been using the Animator.

public class JumpScript : MonoBehaviour
{
    public float jumpHeight;

    void Start()
    {

    }

    void Update()
    {

        if (Input.GetKeyDown(KeyCode.Space))
        {
            GetComponent<Rigidbody2D>().AddForce(Vector2.up * jumpHeight);
            GetComponent<Animation>("PlayerJump");
        }
    }
}

Hi @Maestro_Kitty

gameObject.GetComponent<Animation>().Play("PlayerJump");    // putting "gameObject." is not necessary

All the properties of Animation can be found on the Unity Doc
